[0.8" (2.0 cm)] Due to the relatively low cost, I was a little concerned that these would not satisfy our requirements for the space but man do these deliver. We have 4 of these running on one Sonos Amp in a large living room paired with a Sonos Sub. The speakers are mounted approx. 11ft off the ground on a sloped ceiling. VERY impressed with how they perform!

[6.045 lb] Installed 4 pairs of this in an auditorium of 60ftx40ft. Easy to install, sound quality is great. The wattage tap settings on the front make it easily accessible and simplify refining volume levels of the system especially when mounted on ceiling Also, the System Design Software on jblpro website helped a lot in validating speaker placement.

[6.045 lb] The speakers were delivered promptly. The installation instructions were clear, and the installation was easy except for having to climb a ladder to install them in my ceiling. We use the speakers to play streaming broadcasts and CDs, and the sound has been great.

[0.8" (2.0 cm)] Very good quality, easy installation, just cut a hole in the drywall/sheet rock with the included template, connect the wires, push the speaker into the cut out, the three holding arms will spring into place and you are done. Very good back ground sound for a small speaker.

[0.8" (2.0 cm)] Love the install and sound. Hope I win $1000...

[6.045 lb] How we use this product: We purchased this product to use in a classroom (25'by 30' with 8 ft ceiling). We have a computer connected to this projector and wanted to pass sound through the projector to this speaker. Things that are great: Easy installation - Sounds Great - Sound dispersion of 120 degrees helps hearing it very well all over classroom - Looks very nice attached to ceiling - Sound can also be controlled by projector remote control and/or computer volume control - Volume control on speaker helps balance - Simple directions - Great price! One thing that we have learned is that we can connect several of these speakers together. I also asked the company about connecting a second speaker to this one - they indicated that it is possible to daisy chain up to 6 of these together. (Ask company support for more details.) To complete the install - you will need Bogen Communications PRS2403 24V DC, 300 mA Power Supply and either speaker wire (18 gauge is recommended) and a 3.5mm connector (solder or screw type) or one can purchase a cable with bare wire on one end and 3.5mm connector on the other end. This is used between the speaker and projector audio output. It is a great speaker and it is working great in our school classroom. I would highly recommend this product.

[8 Ω] Speakers are small & blend in nicely in open ceiling environment. Good sound quality for a small speaker. Good sound coverage.

[8 Ω] I installed these in a conference room. Work great, sound great, easy to install.

[6.045 lb] I have installed 8 of these in an new Restaurant there are a fantastic speaker the grill is magnetic which makes them easier to install. The speaker has an extremely low profile the blend right into the ceiling. the centre cone can be adjusted which makes aiming the speaker amazing.

[8 Ω] I used these speakers with JBL 19cs subwoofers for a weight room facility sound system. The total system consisted of 6 - 26c speakers and 4 - 19cs subwoofers. Wiring is made easy with the removable terminal blocks and passthrough wiring. Basically each speaker connects to each other in a line. This installation method reduces cost for speaker wire and labor involved with running extra wire. The terminal blocks have 4 wire holes. For the first speaker in the line will use holes 2 & 3 for the line connecting to the amplifier. Then a wire is ran from speaker 1 to speaker 2. Holes 1 & 4 from speaker 1 connects to holes 2 & 3 on speaker 2. This continues for the entire line. Be sure to properly power these speakers. Both the 19cs and 26c need 140 watts of power. In our installation we used 2 amplifiers splitting the system into left and right sides of the room. Since each amp had 2 outputs of 500 watts for each channel. This provided some headroom for the speakers. On both amps output 1 was was the high and output 2 was the low. Output 1 had 3 26c speakers and output 2 had 2 19cs subwoofers. These amplifiers had a built in crossover feature that splits the signal into high and low frequences which is essential for installing a system like this. A xlr splitter was used to convert the output from the mixer (1 xlr) to inputs for both amps (2 xlr). A cutout template is provided for cutting ceiling tiles. Once tiles are put back in the ceiling the installation can be done without access into the ceiling. The speaker is designed to push up through the cutout in the ceiling tile and clamps down to the C bracket (included). Make sure to have someone assist with installing, these can be insalled with one person but can be difficult for one person to lift, attach wires, put into place, and screw down holders. Overall these speakers work as expected and would buy again. They install nicely and end product looks professional. Nothing less to be expected from JBL.
